- My WAG guess is that you have setup a feedback loop in your soundcard somewhere / creating a distorted snap-shot of the sweep .,,,,snip,,,,It's a an upward curve from 500 Hz to 20 KHz, and I can't get it to change no matter how I set the EQ. But then if I adjust 120 Hz, I hear the difference in the sweep tone and it's directly reflected in the graph. I can swing the EQ settings all over the board, but above 500 Hz the graphs continue to overlay almost perfectly.
Is there a software setting I'm not using correctly?
- A feedback loop will mask most changes made to EQ .
- You need to get into your soundcards bundled software and turn off "Input Monitoring" ( or something named similarly ) if you find it is on .
- Mind you , a feedback loop should have shown up when you calibrated the soundcard ( as the inability to get stable levels ) .
